Purpose: To establish why 16% of 1,045 patients undergoing abdominal and/or
vascular surgery referred to the University Department of Radiology for a
B-image sonogram reported that a US of the same regions of the body had bee
n conducted during the previous 6 weeks without any changes in the clinical
status.
Statement of the problem: Evaluation of the reasons for these superfluous e
xaminations and analysis of the consequences that the US follow-up examinat
ions implied for the patient.
Material and Methods: One senior resident radiologist and one senior reside
nt surgeon reviewed the medical records of the patients reporting previous
examinations and examinations scheduled at the time of the questioning of t
he patients.
Results: One hundred and eight (63%) of the 171 medical records were availa
ble. Data on previous examinations mentioned in the report forms were incor
rect in 14 cases (13%). Therefore, further evaluations were based on 94 pat
ients. Ten (8%) out of 121 sonograms, 4 (10%) out of 40 CT and 2 (20%) out
of 10 MR investigations documented in the medical records had not been ment
ioned by the patients. As many as 41 (75%) of the 55 preliminary sonograms
performed by general practitioners and specialists in private practice were
not documented in the medical records. Even though records existed of clin
ically plausible findings, 36 (84%) of the 43 preliminary US investigations
performed by doctors in the University Hospital were repeated to verify th
e diagnosis without any further diagnostic benefit.
Conclusion: A cross-speciality consensus over the diagnostic value of B-ima
ge sonography and management of the findings obtained is of paramount impor
tance.
